Petrol Smell

Post by Scott »

Hello..

I'm getting a really strong smell of petrol fumes. Most noticeable when I first get in, and when driving with the windows down.

Any advice?

sounds more like a fuel leak around the fuel tank area, opening the windows will draw air through from the boot into the cabin. Check the condition of the filler neck and that you don't have any drip underneath the car

There is a little plastic box just underneath the front scuttle on the LHS. There are breather hoses from the tank into this. Check if this stinks of fuel. It might just need cleaning.

Cheers for the advise.... I'll have a little look around it.

Strange thing is that the breather pipe direct from the tank has a bung in it. I took this off before the smell was bad, and connected it up to the tube laying next to it. The smell then seemed to be worse, so I bunged it back up... and now it's worse still!

Hi, Check the fuel cap is on properly? :)

I had a smell in mine for weeks as you describe, which went away next time I filled up... :oops:

I get a similar smell but I put it down to the fuel ventilation system on the car as it's a US model.

On older cars the 'gland' around the tank sender unit - along with the clip to the filler neck can both perforate / wear - worth checking both. Had the same problem with LYV 10D and discovered the drain hole seal was worn - 10p washer and the problem was sorted :roll:

Cheers guys....

Had a good look around last night. Filler cap is on ok, and can't see any leaks from underneath of the car. The smell when outside the car seems to be strongest around the wheel arches. Do all of you guys use the breather pipes, rather than bunging them up like mine? I'll have a look around the filler neck as well.

Matt mines also a US model..73.

Had a similar problem which was due to faulty fuel filter -potentially quite dangerous

I had the same problem but cured it by replacing the gasket on the filler cap.
